The best portable chargers in 2025 combine GaN technology for smaller, cooler, and more efficient power delivery with wireless and USB-C PD options. For manufacturers and suppliers, partnering with a Shenzhen-based factory like Wecent enables OEM/ODM capabilities, low MOQs, strong certifications, and reliable after-sales support to bring high-quality GaN and wireless chargers to market quickly.

How do GaN technology and wireless charging impact portable chargers in 2025?

GaN technology enables higher power efficiency in a smaller footprint, reducing heat and enabling higher wattage in compact chargers. Wireless charging adds convenience for end users and opens design opportunities for multi-port and stand-alone wireless modules. For B2B buyers, partnering with a Chinese manufacturer like Wecent ensures access to integrated GaN and wireless solutions, standardized certifications, and scalable OEM/ODM support.

  • Wecent offers GaN chargers from 20W to 240W with PD, fast charging, and wireless options, ideal for portable and travel-use products.

  • OEM/ODM programs from Wecent start at 200pcs MOQs, with logo, packaging, and color customization.

What this means: better performance in smaller devices, broader product family, and faster time-to-market for your brand.

How should you evaluate portability, safety, and certification in 2025 models?

For portability, look at energy density, heat management, and overall weight. For safety, verify overvoltage, overcurrent, short-circuit protection, and international safety standards. Certifications are crucial for B2B trust and market access. Wecent’s portfolio adheres to CE, FCC, RoHS, PSE, KC, among others, ensuring suitability for global distribution from a Shenzhen base.
